How to Detect Abnormal Pricing?
“Money Laundering and Income Tax Evasion: The Determination of Optimal Audits and Inspections to Detect Abnormal Prices in International Trade,” Journal of Financial Crime, Vol. 12, No. 2, 2004. (de Boyrie, M.E., Pak, S.J., and Zdanowicz, J. S.)
Audits & Inspections Customs Agents
Lack of benchmark pricing data (arm’s length price) - Difficult to determine abnormality
Pre Shipment Inspection firms All specified inbound cargos inspected
Challenges in Detection Over 70 million transactions annually in U.S. Exports
and Imports Examination of trade documents Physical inspection of cargo Delays in the movement of goods
Seminar on Public Finances and Tax Evasion in Latin America, Aug 25-26, 2010… 19
How to Detect Abnormal Pricing?
Alternative Approaches: Computerized Filtering based on benchmark
prices if available Low cost & efficient Accurate
A statistical approach by estimating upper & lower bounds if benchmark prices not available
Low cost and efficient Accuracy depends on the quality of the historical
data in estimating the benchmark upper & lower bound prices
Seminar on Public Finances and Tax Evasion in Latin America, Aug 25-26, 2010… 20
How to Detect Abnormal Pricing?
Statistical Approach Estimate the benchmark upper and lower
bounds of prices (Price filter matrix) Based on statistical Analysis of historical prices For each commodity category by country
Transactions with prices outside the benchmark prices
Higher probability of being abnormal than the population
The narrower bounds of the benchmark prices, the more numerous the transactions with prices outside the benchmark prices
Suspected trades with abnormal prices require inspections by Customs agents
Seminar on Public Finances and Tax Evasion in Latin America, Aug 25-26, 2010… 21
DATA SOURCE Import and Export data from U.S. Customs and
Border Protection Most detailed import and export records Not publicly available
U.S. Merchandise Trade Data from U.S. Census Bureau
Publicly available Import and export records grouped by HS10, Partner
country, customs district, and month 8,750 export HS10 codes and 16,703 import HS10 codes in 2009 233 countries in 2009 44 customs district codes

Price Filter Matrix - Criteria for Price Abnormality
Price Filter Matrix may be constructed from the U.S. Merchandise Trade data: For each commodity code and each country
The average price, the standard deviation, upper- and lower- bound pricesUpper bound = the mean + as or Upper Quartile
PriceLower bound = the mean - as or Lower Quartile Price
Total Number of Cells in 2009: 5.86 million cellsExport: (8,750 items)x (233 countries) = 2.04 mm cellsImport: (16,703 items) x (229 countries) = 3.82 mm cells

Detection of Abnormal Pricing
Physical auditing/inspection Too many to inspect – costly & delayed cargo flow Benchmark prices available for limited number of items
Computerized detection with benchmark prices Low cost and accurate Benchmark prices available only for limited number of items
Computerized detection with statistically estimated Price Filter Matrix Less accurate than with benchmark prices Possible underestimation of abnormality Efficient and low cost detection of importers/exporters with
frequent mispricing when combined with inspection/audit by Customs specialist
Seminar on Public Finances and Tax Evasion in Latin America, Aug 25-26, 2010… 38
Outline
Abnormally priced export and import Guatemala’s export examples – Bananas and Coffee Guatemala’s import examples – Wheat and Light
Crude Oil Causes and Effects of abnormal trade pricing
Detection methods of abnormal pricing Arm’s length price (ALP) data Price filter matrix – a statistical approach
Estimates of capital flows through abnormal pricing: LAC countries vs. U.S. (tax haven?)
Non-quantified trades Commodities with volatile price movements
Summary Detection system – Price filter matrix & its limitation
Seminar on Public Finances and Tax Evasion in Latin America, Aug 25-26, 2010… 39
Estimates of Capital Flows using Price Filter Matrix
METHOD: Estimate upper and lower quartile prices for:
Every commodity Every country
Calculate overpriced amount and underpriced amount for every trade with prices outside the interquartile range
Aggregate overpriced amounts and underpriced amounts for all trades
CAUTION: The method can’t be applied to non-quantified trades The price filter method will not work for commodities with
volatile benchmark prices such as crude oil in 2008

Limitations of Price Matrix Filter Approach
For highly heterogeneous HS10 categories
The price filter matrix may introduce biases Wider upper/lower quartile ranges mitigate
the biase problem somewhat Aggregated data
By HS10, Month, Country, and Customs District
No distinction between Related party transactions v.s. unrelated
party transactions HS10 categories without quantity
reported No price filter matrix can be constructed
Seminar on Public Finances and Tax Evasion in Latin America, Aug 25-26, 2010… 52
Limitations of Price Matrix Filter Approach
Inter-quartile price range is somewhat arbitrary
Automatically classify top 25% and bottom 25% as abnormally priced
But the U.S. IRS transfer pricing regulation (IRC 482) specifies that an inter-quartile range is an acceptable arm's length transaction range
Seminar on Public Finances and Tax Evasion in Latin America, Aug 25-26, 2010… 53
Why use Price Filter Matrix?
A good first-order approximation in estimating abnormality
Detection of abnormality The price filter approach based on the inter-
quartile range is an effective initial step in investigating and identifying truly abnormally priced trades
Needs follow-up inspections
Seminar on Public Finances and Tax Evasion in Latin America, Aug 25-26, 2010… 54
Proper Application of Price Filter Matrix
Examine the frequency of abnormally priced trades for a particular importer or exporter The probability of a randomly selected
transaction to be above upper-, or below lower-quartile range is 25%.
The probability for a half or more of 100 transactions to be above upper-, or below lower-quartile range is 1 in 47 million chances!
Therefore, the price filter approach based on the inter-quartile range can be an effective tool in detecting importers/exporters with frequent mispriced transactions.

Other Factors in detecting Suspicious Cargo
Easy computerized detection:• Suspiciously high/low shipping cost
per unit weight• Abnormal weight: a spark plug
weighting 4 pounds?
Seminar on Public Finances and Tax Evasion in Latin America, Aug 25-26, 2010… 56
What about High Shipping Cost?
Why would Shipping Costs be higher than Customs Values? For Exporters: Another way of moving
capital/wealth through trade For Importers:
Raise the cost of goods reducing taxable income Reduce customs duty

Impacts on the country Reduced tax revenue Capital flight Distort balance of trade statistics

SUMMARY
Price Filter Matrix Can be built for each HS code & country
combination May be effective in identifying abnormally
priced import and export transactions when combined with inspection by customs specialists
Can be used for real-time inspection of cargo
